We computed the feature vectors of the Cora dataset
[1]}, which is a
research citation network (directed) comprising of 2708 scientific
publications classified into one of seven categories.
In this experiment, nodes that represent a given topic cluster together
and also move away from topics that are different. We see this
separation improve as we vary the number of iterations \(H\)  from 4 to 6.
